Lucifer conducts a train full of condemned souls, including Ms. Merrywood, back up to Heaven. As the train approaches Heaven’s gates, Ms. Merrywood discovers a horseshoe pendant and the condemned souls begin singing hymns (‘’Shovel and Bone’’). In Heaven, God discusses the crisis with his top dog, The Agent. The Agent and The Translators, officers in Heaven’s police force, interrogate Merrywood about her presence and the pendant. In Hell, the Ticket-Keeper warns Lucifer that the carnies are not prepared for a war with Heaven, but Lucifer dismisses him to entertain a cloaked figure. Lucifer opens his book of Aesop’s Fables and reads “The Filly and The Lapdog” to the cloaked person.
In flashback, a new crop of Applicants arrive in Heaven, including best friends June and Cora. They are welcomed into Heaven and are offered a tour of the premises (‘’All Aboard (Everybody’s Doing The Ark’’). June defies The Librarian about banned books in Heaven and steals a Number 1 armband from The Designer, who keeps the Number 7s working in a windowless design shop, that starkly contrasts with the grandeur of the Heaven lobby (‘’Only By Design’’). June’s rebellious nature makes her and the reserved Cora wander around Heaven, only to be arrested and interrogated by The Translators (‘’Good Little Dictation Machines’’). The Agent intervenes, and there is a mutual attraction between him and June, which gets him negative press from The Watchword. When God becomes aware of this, he orders The Agent to seduce June to expose her heresy.
The Agent brings June to a bar, Club Cloud Seven, where his closeness with God leads him to be invited to sing (‘’Down at the Midnight Rectory’’). God arrives and serenades one of his girlfriends (‘’Cloud Serenade’’). The Agent and June’s relationship continues, always under the watchful eye of The Watchword (‘’The Watchword’s Hour’’). The Watchword confronts Cora, warning her that her lesbian attraction to June is forbidden and illegal in Heaven. The Agent reignites June’s curiosity with banned material and she runs off to steal a restricted book. Confident that The Agent’s clout will protect her, she steals a book, setting off an alarm. June is beaten by The Translators and tossed down an elevator shaft leading to Hell. Meanwhile, The Librarian instructs Cora and the other Applicants to denounce June, and spend the rest of the night restoring order by re-shelving Heaven’s library with him (‘’Hitting
